No, Roh'Lieris is not elven for "Castle of Destiny". "Castle of Destiny" is a subtitle. Please don't get confused.

As an additional note, please do not confuse the Castle of Destiny with the Castle of Density. There have been many an unfortunate elven adventurer seeking their destiny only to find a castle with a very large value for d. While quite interesting, it more often than not has no bearing on one's destiny.

Except for the adventurer dense enough to confuse destiny and density.
